Once the money from a new tax starts coming in, its hard to rescind the tax because now you have to find the money somewhere else, or make a cut somewhere. Changing a gun law is fiscally painless. They did it in VA with the one gun a month requirement. They also repealed all the local laws so that the same rules applied statewide. I can remember years ago buying a 1911 Colt Gold Cup from a gun shop in Alexandria. I payed my money, filled out the paperwork and was good to go. OK, the guy says, you can pick up your gun next Tuesday. WTF? Oh, Alexandria has a five day waiting period.
